Yes, it is not well documented or published as S3. But the dude has CDN support, which the S3 lacks (unless you want to pay extra, of course). It's bad that you cannot FTP in Mosso CloudFile, you either have to upload it via the web control panel or API. However, it is still cheap and costs especially with CDN.
I use this service and it is pretty good and economical compared to S3.
